There is no standard clinical answer to the question of how many times an abortion can prevent pregnancy, because clinically, if each abortion has no complications, does not affect menstruation, has no inflammatory reaction, and the uterine lining is not damaged, clinically, even if the abortion is performed 4 or 5 times, it will not affect fertility. However, if there are serious complications after only one abortion, such as severe pelvic inflammatory disease, resulting in tubal adhesion, clinically it is impossible to get pregnant again. If the damage to the endometrium after abortion causes incomplete adhesions or complete adhesions in the uterine cavity, even after clinical hysteroscopic surgery and separation, the chances of getting pregnant in the clinic are significantly reduced. So in the clinical abortion several times can not have children, mainly depends on the abortion whether the corresponding complications.
